Introduction and Testbed Setup

Western Digital (WD) introduced hard drives specifically targeted towards NAS systems under the Red branding last month. Jason had some initial coverage at launch time. WD claimed to have put in a number of firmware features and some additional hardware aspects in the Red lineup to make it suitable for NAS usage.

WD touted the following main points

  • Less aggressive head parking (no IntelliPark feature)
  • Configurable Time Limited Error Recovery (TLER), with a default of 7 seconds
  • IntelliPower disk rotation speeds (comparable to Green drives)
  • Vibration reduction mechanism in hardware
  • 3-Yr. warranty and 24x7 phone support

In the next section, we will analyze each of these claims in detail. First, let us take a look at the testbeds. We used the WD Red drives standalone in a PC and also as part of a few SMB / SOHO NAS systems. Our standalone PC testbed was also used for some of the NAS testing. Our Summer 2012 NAS testbed's specifications are provided below:

NAS Benchmarking Testbed Setup [ Summer 2012 ]
Processor Intel i7-3770K CPU - 4C/8T - 3.50GHz, 8MB Cache
Motherboard Asus P8H77-M Pro
OS Hard Drive Seagate Barracuda XT 2 TB
Secondary Drives Western Digital Red WD30EFRX 3 TB
Corsair Performance 3 Series™ P3-128 128 GB SSD (Offline in Host OS)
Memory G.SKILL ECO Series 4GB (2 x 2GB) SDRAM DDR3 1333 (PC3 10666) F3-10666CL7D-4GBECO CAS 7-7-7-21
PCI-E Slot Quad-Port GbE Intel ESA-I340
Case Antec VERIS Fusion Remote Max
Power Supply Antec TruePower New TP-550 550W
Host Operating System Windows Server 2008 R2 Enterprise
.

A Windows 7 virtual machine was set up using Hyper-V with the following configuration

Windows 7 Ultimate x64 : Guest OS
Processor Single Physical Core of Intel i7-3770K
OS Hard Drive VHD File on Seagate Barracuda XT 2 TB
Secondary Hard Drive Corsair Performance 3 Series™ P3-128 GB SSD
Memory 1 GB

The following NAS units were used for testing the WD Red drives in RAID-1 configuration.

  • LaCie 2big NAS
  • Netgear NV+ v2
  • Synology DS211+

The drives were benchmarked against 2 x 3TB Seagate Barracuda 7200rpm drives that were bundled with the LaCie 2big NAS.

An important aspect of NAS systems that we haven't covered in detail is the effect of prolonged usage and how differently the NAS performs when it is close to full capacity. Towards this, we also used our build-in-progress NAS testbed to stress the WD Red drives in the Synology D211+. The details of this separate testbed and methodology are described in a later section.

    An 80mm and 120mm fan keep them idling at about 36C (and they are pretty quiet about it) in a relatively cramped case. Even under extreme prolonged load I would be surprised if they ever got over 55C. My thermostat stays at 25C/78F.

    As for thermal cycling, I admit that I leave the thing running 24/7 which probably costs me a pretty penny over the long haul. I keep meaning to plug it into my killawatt out of curiousity.

    I wouldn't mind paying a little extra for the 3 year warranty, but for what these things cost I could buy a couple green hot spares and still come out $150 ahead (using 2TB drives).

    For a home NAS, green is the way to go. Just turn off intellipark. If you're leery of all the bad hype with the WD green drives, samsungs cost the same price and I've had good luck with those for about two years as well now. If you are using any sort of mass storage without a reasonable level of redundancy and regular backups you are just asking for trouble.

    I was moderately interested when the red line was announced, but I can't see any added benefits that justify the premium price.

    Your sentiments will be shared by others, thus keeping RED drive volumes low, and this will lead WD to drop prices to where they are supposed to be.
    Just wait a while and watch.

    Hard drives exceeding 45C start to fall off rapidly in terms of cycle life, while the RED drives may perform as well with temps reaching as high as 55C. The RED drives below 45C are likely to last a very long time with load/unload cycles of 600,000 matching Enterprise drives.

    It isn't so much the testing methodology is flawed, but the reviewed drive model for the Seagate drive. Seagate has been making 7200rpm Barracuda with 1TB platters (non-XT) for quite some time, yet only the 500GB platter version of Barracuda XT is used in this review. If Barracuda XT must be used for the test, it should be the 3TB version, which has slightly higher density (600GB), or the Seagagte Constellation ES.2 counterpart. Reply

    Never mind the 2TB claim, the test did use the 3TB drive. But still, the tested Seagate drives have such huge density disadvantage, it's disappointing that Barracuda XT/Constellation ES don't have the new terabyte platter models. Reply

    Just ordered 14 of these for a Supermicro 24 drive bay chassis. Crossing fingers we won't have any issues with the LSI 2108 controller and these drives. Reply

    EXCLUSIVE NASWARE TECHNOLOGY.

    The secret is in the technology.
    WD’s exclusive NASware technology improves NAS storage performance by reducing common hard drive concerns in NAS systems including concerns for things like compatibility, integration, upgrade ability, reliability and cost of ownership that are experienced with a hard drive designed for desktop computers. Our exclusive technology, NASware™, makes WD Red thrive in the demanding small-NAS environment.

    NASware Enhanced reliability.
    Your NAS systems is always on, a highly reliable drive is essential. With a 35% MTBF improvement over standard desktop drives, the WD Red drive is designed and manufactured to be a more reliable and robust solution.

    NASware 3D Active Balance Plus.
    Our enhanced dual-plane balance control technology significantly improves overall drive performance and reliability. Hard drives that are not properly balanced may cause excessive vibration and noise in a multidrive system, reduce the hard drive life span, and degrade the performance over time.

    ================ WD speaks with forked tongue ====================
    CAVEAT EMPTOR
    So now we have a better balanced drive to reduce noise, vibration and improve drive life cycle. Are we made to believe this requirement of RED drives is only needed in a 24/7 NAS environment? This is rubbish, balanced drives are needed everywhere.

    Desktops running for 8 hours every day is certainly ON for a long time and qualifies as 24/7. But is it not also true that unbalanced drives in a desktop will also reduce drive cycle life? So why is it OK to put such unbalanced drives in desktops which are expected to last just as long as NAS systems? Why is it OK to put a lower quality drive in a desktop and insist a better quality drive is needed for NAS.

    Pure Crap. Desktop drive cycle life is just as important. Why is it OK to increase the risk of a drive crash on a desktop, while one goes to great pains to reduce this risk on a NAS system?

    BALANCED DRIVES ARE NEEDED ON DESKTOPS TOO.

    Western Digital is admitting that GREEN and BLUE drives are CRAP and not suitable for desktops, in part because they are not suitably balanced. Or put another way, they have designed the cheaper drives to be less balanced by design, and dictate that desktops will be subjected to higher reliability risks in terms of disk crashes. By their own admission inadequately balanced drives lead to reduced cycle life. In reality there is no difference between NAS and DESKTOPS in terms of needed cycle life, and what is plainly obvious is that RED drives really constitute a MINIMAL quality for desktop too.

    MARKETING BROO HA HA - just another fancy term for Corporate lying.

    DRIVE BALANCE IN A SINGLE DRIVE SYSTEM IS JUST AS IMPORTANT AS IN A MULTI- DRIVE SYSTEM FOR THE PURPOSES OF IMPROVING DRIVE CYCLE LIFE. Marketing not withstanding.

    What we need is a way of measuring drive balance quality in hard drives, and stick it to them when reviewing these hard drives. We need to be able to measure the WOBBLE FACTOR to gain control over drive quality assessments.

    If these "red" drives are so much better, and more durable, than their "black" drives... why do the "reds" have a 2 *YEAR* shorter warranty????

    (anandtech foolishly compares warranties only on the drives that are even LESS than the "reds".)

    As a photographer I'm concerned at the low throughput of the NASPT photo album. Why is the throughput so low? Reply
